FWIW, the crew in the video needs to fully release the main until the boat stopped, then they could trim it a bit if they wanted to adjust how the boat sits off the wind.
As their jib pushes the bow off, the main pushes it up, if the main is trimmed enough, it'll tack the boat, backed jib or no.
Certified...in several regards...
